STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

Not Applicable.

FIELD

The present invention relates to pharmaceutically acceptable formulations of orally administered substances, and more particularly to formulations for orally administering substances, the individual formulations being administrable in either a dry powder form or with a small quantity of water (as preferred by the subject), and to methods for preparation and administering the substances.

INTRODUCTION

Patient acceptance of medications, often referred to as patient adherence, has been reported to average 50% in developing countries around the world (1). Although a number of factors may contribute to the 50% lack of adherence, characteristics of the drug formulation may be of particular importance. For example, oral tablet formulations can sometimes cause dysphasia and/or nausea and vomiting in patients (2). Further, unpleasant taste may be a challenge in administering a medicine particularly for children (3, 4).

Ibuprofen is a commonly used non-steroidal anti-inflammatory drug (NSAID) with multiple beneficial effects including pain relief and reduction of inflammation and fever. (5, 6). Nevertheless, patient adherence may be a challenge in treatment with ibuprofen as well as other NSAIDs (7, 8).

Additionally, formulations which are administrable both in dry powder form and in suspension by adding a minimum quantity of water to dissolve the dry powder are not available on the market. Powder, solution, and suspension dosage forms typically utilize a different set of excipients to achieve acceptable physical properties. For a powder, excipients are chosen on the basis of achieving acceptable physical properties such as flow, density, and compactibility. For a solution and suspension dosage forms, excipients are chosen on the basis of achieving acceptable properties such as solubility, suspendability, dispersability, and viscosity. For flavored powders, solutions, and suspensions, the type and concentration of sweeteners and flavors are typically different since the sensory perception of flavor and texture would be different when consuming a powder versus a liquid dosage form. Also, taste masking of active pharmaceutical ingredients (API) are typically dependent on type, concentration, and processing method (i.e., API coating, granule coating, etc.) of excipients.

Therefore, what is needed is a formulation which is administrable both in dry powder form and in suspension by adding a minimum quantity of water to dissolve the dry powder.

SUMMARY

Accordingly, the inventors herein have succeeded in devising formulations that can be administered either as a dry powder or in a small quantity of water. The new formulations provide improved taste and mouthfeel to facilitate ease of administration and patient adherence.

Thus, in various embodiments, the present invention is directed to dry-powder oral formulations that include an active pharmaceutical ingredient (API), a lecithin powder, a galactomannan, one or more sweetening agents, one or more flavoring agents and an organic acid in a pharmaceutically acceptable preparation.

In various aspects, the formulation solubility or dispersability in water is no more than about 0.5 w/v. In various aspects, the formulation or an aqueous solution or dispersion thereof is in a unit dosage form in a container selected from the group consisting of a blister foil pack, stick pack, sachet, pouch, bottle, orally disintegrating tablet, dispersible tablet, capsule, powder in a capsule, and spheres in a capsule.

As used herein, the following terms are defined with the following meanings, unless explicitly stated otherwise.

The term “about” when used before a numerical designation, e.g., pH, temperature, quantity, concentration, and molecular weight, including range, indicates approximations which may vary by ±5%, ±1%, or ±0.1%.

As used in the specification and claims, the singular form “a”, “an” and “the” include plural references unless the context clearly dictates otherwise. For example, the term “a pharmaceutically acceptable carrier” may include a plurality of pharmaceutically acceptable carriers, including mixtures thereof.

Formulations

In various embodiments, the present invention is directed to an excipient composition comprising a lecithin powder, a galactomannan, one or more sweetening agents, one or more flavoring agents and an organic acid in a preparation that when combined with an API produces a pharmaceutically acceptable preparation.

The invention utilizes functional excipients to produce a powder such that the following are achieved:

-   -   1. Acceptable properties of flow, density, compactibility,         suspendability, and dispersability are achieved for powder,         solution, and suspension dosage forms.     -   2. Acceptable flavor profiles (intensity of flavor) and         sufficient taste masking of one or more active pharmaceutical         ingredients in the dosage forms listed in item 1 without the         need for complex taste masking methods.     -   3. The same powder formulation can be processed utilizing but         not limited to dry blending, roller compaction, wet granulation,         spheronization and filled into foil/stick packs/sachets/pouches,         compressed into chewable/swallowable/quick dissolving tablets         and filled into capsules.     -   4. The invention allows for the powder dosage form to quickly         dissolve in the mouth or the powder can be readily dissolved or         suspended and dispersed using a small quantity of water and then         taken by mouth.

In various embodiments, the formulation is a dispersion comprising ibuprofen, guar, lecithin, and flavors. In such a dispersion, isomalt, xylitol, citric acid, can be solubilized. In various other embodiments, the formulation can comprise components which are all solubilized.

Lecithin refers to a group of amphiphilic, surfactant compounds naturally occurring in plant and animal tissue and pharmaceutically useful as emulsifying agents. Lecithins can be found in fish, eggs, milk, soybeans, cotton seed, rapeseed and sunflower seeds. Chemically, the central structure of lecithin is a glycerol group with ester linkages to two long chain fatty acid groups and to an orthophosphate group. The orthophosphate group is then linked by an ester bond to a strongly basic choline group (12). The resultant molecule as shown below is a surfactant:

In processing from plant sources, the extract may be in oily liquid form as a result of the presence of liquid oily components which when further removed yields a granular or powder product.

Sunflower lecithin powder contains phosphatidyl choline, phosphatidyl inositol, phosphatidyl ethanolamine, and phosphatidic acid. In contrast to this, lecithin oil additionally contains oily components that result in the composition being in the form of an oily liquid.

The term “lecithin” or “lecithin powder” as used herein is intended to reference lecithin in powder or granular form and not lecithin oil.

The lecithin powder may be present in the excipient composition as well as in compositions containing an API and the excipient composition in an amount of from about 0.1% w/w, about 0.2% w/w, about 0.4% w/w up to about 0.6% w/w, about 0.7% w/w, about 0.8% w/w, about 0.9% w/w or about 1.0% w/w and, in particular, in an amount of about 0.1% w/w, about 0.2% w/w, about 0.3% w/w, about 0.4% w/w, about 0.5% w/w, about 0.6% w/w, about 0.7% w/w, about 0.8% w/w, about 0.9% w/w or about 1.0% w/w.

The term “galactomannan” refers to a polysaccharide containing a mannose backbone and galactose side groups. Galactomannans may have a mannose to galactose ratio of from about 1:1 to about 4:1 and non-limiting examples include fenugreek gum, guar gum, tara gum and locust bean gum. Guar gum, in particular, may be useful as a component in the formulations herein.

When taken wet with 5 g of filtered water, flavor and sweetness was comparable to dry intake with very low level of burning.

This Formula went into solution easily except that the ibuprofen seemed to agglomerate and form a film at the top. The formulation needs a natural surfactant so that the ibuprofen will disperse uniformly into the water.

The data demonstrates that chewable, swallowable and/or orally disintegrating tablets can be produced with good weight control, acceptable thickness and breaking force.

This formula with the magnesium stearate is functional for the dry powder dosage form, suspension dosage form and the chewable tablet. Those of skill in the art will recognize the other lubricants including but not limited to stearic acid, calcium stearate, sodium stearate, sodium stearyl fumarate (PRUV®), talc, and hydrogenated soybean oil (STEROTEX®) can be used in the formula.
